The answer should be 3 :)
(4/7)w = 12/7
w = (12/7) / (4/7)
w = 12/7 * 7/4
w = 84/28 = 3....it would take 3 weeks
The correct answer is x=18
Answer:
Infinitely many solutions.
Step-by-step explanation:
Multiply the second equation by -2, then add the equations together
(20x+2y=18)
−2(10x+y=9)
20x+2y=18
−20x−2y=−18
Add these equations to eliminate x
0=0
Infinitely many solutions.
